Justin's career hinges on international travel, which would become complicated if the pop star is convicted.

Justin Bieber has had a narrow miss with the law in recent weeks, having been released on bail after his DUI in Miami. Unfortunately for the singer, it turns out his legal woes might endanger his career in a big way. On Friday evening, the private jet carrying Bieber from Canada to New York for the Super Bowl parties, was detained was detained at the Teterboro, N.J. airport after officials noted that they smelled marijuana. According to USA Today, Bieber was released following a thorough search and several hours of questioning, which yielded no evidence against him.

Justin's career could be in jeopardy thanks to the charges.

While the singer is off the hook on that charge, the charges against him – DUI and assault in the US and his native Canada respectively – still stand. In reverse order – this week, Bieber was charged with assaulting a limo driver in Toronto, last week came the infamous DUI arrest, after which a toxicology report noted the presence of pot and the prescription anti-anxiety drug Xanax in his system. Additionally, Justin is still under investigation for egging his neighbor’s house in LA.

The pop star has two trials scheduled for February.

The three different charges could become a real problem for Bieber in terms of international travel. If the singer is convicted of anything, international travel would become a headache, with his immigration status scrutinized on every trip. In addition, every item on his itinerary would have to be approved by a judge.
